Celebrating Summer Solstice

A group of people look at the horizon standing on the rocky crest filled with astronomical markers at the megalithic observatory Kokino, soon after sunrise, early morning of the Summer solstice. The ancient astronomic observatory, located about 100 km northeast of Skopje, the capital of the Republic of Macedonia, dates more than 4.000 years back in time. It is ranked by NASA as the fourth ancient observatory in the world.
